In a statement the Aix-en-Provence appeal court said the German agency had “respected the obligations incumbent upon it as a certifying organisation”.
Poly Implant Prothèse (PIP), the French company at the centre of the scandal, sold implants globally, incluing hundreds in Ireland, over almost two decades until investigators discovered it was passing off industrial silicone as a much pricier medical product.
The counterfeit substance was used in implants given to some 300,000 women. About one-quarter of those subsequently removed were found to have ruptured, regulators said, raising concerns over the long-term health effects of exposure to their contents.
Company founder Jean-Claude Mas was jailed for four years and fined €75,000 in 2013 after an investigation revealed a fraud.
PIP employees would remove evidence of the cheaper silicone gel before annual inspections by TUV Rheinland, it found.
“TUV Rheinland welcomes this verdict,” the agency’s lawyer, Cécile Derycke, said on Thursday.
“The fraud committed by PIP could not have been detected by TUV Rheinland with the tools granted to certification organizations under current regulations.”
